interface ?'s

after reading through the text i think i see the connection between blade runner and the interface, but Is the article about connecting the two or about the interface itself?
i see the connections that they rule contemporary culture, and both have been built on and concepts have evolved from the originals that creates much of modern day culture but i feel as the author was using it as a connection for and introduction and it was not meant to be dwelled upon throughout the article.
a quote from page 67 ," to change the interface even slightly is to change the work dramatically" this quote struck my memory to a quote from the movie and helped me to make a connection in the text

i found the connection between the "non-transparency of the code" concept and the Whorf- Sapir hypothesis very confusing what point was the author trying to make in this part of the article?
